Ina further example, the location guide 20 may be provided to align thebasestation radio module 12 or the basestation module platform 14 withany electronic modules. In a further example, the basestation system 2may include more than one tower mounted equipment 10, and may includemore than one location guide 20 for more than one tower mountedequipment 10.

A cabling and pulley system having a cable 40 and a pulley 42 isprovided to the basestation system 2. In FIG. 1, one set of the cable 40and the pulley 42 is provided to each side of the tower mountedequipment 10. The pulley 42 is connected to the connection plate 16.However, in another example, the pulley 42 may be connected to thestructure of the tower 4. The cable 40 is connected to the basestationmodule platform 14. The basestation radio module 12 is located byraising or lowering the basestation module platform 14. However, inanother example, the housing of the basestation radio module 12 may bedirectly raised or lowered by the cabling and pulley system.

A winch system 44 is provided to wind up the cable 40. The winch system44 with the cabling and pulley system enables the basestation radiomodule 12 to be raised or lowered from the masthead.

In order to prevent damage to the communication cable 32 connecting thebasestation radio module 12 to the network connection, the basestationsystem 2 uses a plug and socket arrangement such that the communicationcable 32 is disconnected from the basestation radio module 12 when thebasestation radio module 12 is lowered from the tower top, and isconnected to the basestation radio module 12 when the basestation radiomodule 12 is raised and is positioned at the tower top.

In FIGS. 1-2, the communication cable 32 is attached at the top of thetower 4 to the connection plate 16 so that the basestation radio module12 can be removed from the basestation module platform 14 and replacedor serviced, without having to bending the communication cable 32 whenthe basestation radio module 12 is lowered from the top of the tower 4.

In some radio towers there may be a requirement to service multipleoperators' equipment. In such a scenario multiple antenna locationplates may be present at various heights along the vertical axis of themast. In such a scenario each operator's equipment may incorporate aseparate winch system for location of the base station equipment. Inaddition, in the case where the multiple operators use the tower,multiple fixed communication cables may ascend the tower.

In FIG. 3, a connection plate 16A with blind mate connectors 54 is shownas an example of the connection plate 16 of FIG. 1. The connection plate16A is secured to the tower top. The main and diversity antennas 52 aremounted on the connection plate 16A. The connection plate 16A enablesconnection of the basestation RF transceiver unit 12A to the main anddiversity antenna 52. The communication cable 32 is attached to theconnection plate 16A. The connection plate 16A also enables connectionof the basestation RF transceiver unit 12A to the communication cable32. The communication cable 32 is not subject to bending associated withit having to follow the basestation RF transceiver unit 12A down thetower.

In FIG. 3, the connection plate 16A is provided for one basestation RFtransceiver unit 12A. However, the connection plate 16A may be modifiedto accommodate multiple RF basestation transceiver units in the casethat multiple service providers are connected to the tower.

The enclosure of the basestation RF transceiver unit 12A incorporatesblind mate connectors 56 into its top surface. The blind mate connectors56 in the enclosure of the basestation RF transceiver unit 12A arecoupled with the blind mate connectors 54 in the connection plate 16A.The blind mate connectors 56 may be encompassed by a rubber ‘O’ ringseal to prevent water ingress.

In FIG. 3, the blind mate connectors 54 are formed in the connectionplate 16A. However, in another example, the blind mate connectors 54 orany other connection mechanism for connecting the RF transceiver unit12A to the antenna 52 may form part of the structure of the tower or maybe formed in the housing of any electronic modules. In a furtherexample, the antenna module associated with the antenna 52 may have aconnection mechanism and be connected to the RF transceiver unit 12Awithout using the connection plate 16A.

In FIG. 3, location guide rods 60 and location alignment holes 62 areshown as an example of the location guide mechanism 20 of FIG. 1. Thelocation guide rods 60 slide into the location alignment holes 62. Thelocation alignment holes 62 receive the location guide rods 60 tofacilitate blind mate electrical connection of the blind mate connectors54 and 56.

In FIG. 3, the location guide rods 60 are attached to the connectionplate 16A and the location alignment holes 62 are arranged in thehousing of the basestation RF transceiver unit 12A. However, in anotherexample, the location guide rods 60 may be attached to the housing ofthe basestation RF transceiver unit 12A, and the location alignmentholes 62 may be arranged in the connection plate 16A.

In another example, the location guide rods 60 may be attached to thehousing of the antenna system (e.g., 18 of FIGS. 1-2, 52 of FIG. 3) orany other electronic modules. In a further example, the locationalignment holes 62 may be formed in the housing of the antenna system(e.g., 18 of FIGS. 1-2, 52 of FIG. 3) or any other electronic modules.In a further example, the location guide rods 60 or the locationalignment holes 62 may be formed in the structure of the tower.

In a further example, the location guide rods 60 or the locationalignment holes 62 may be arranged in the housing of any basestationmodule(s) on the basestation module platform 14 other than thebasestation RF transceiver unit 12A.

In a further example, the location guide rods 60 and the locationalignment holes 62 are arranged such that the location alignment holes62 are formed in the basestation module platform 14. This arrangementenables the location alignment holes 52 to be removed from thebasestation RF transceiver unit 12A, and thus it may reduce the size ofthe basestation RF transceiver unit 12A.

in a further embodiment, the communication cable 32 of FIGS. 1-3 may besufficiently flexible to sustain the mechanical bend radii associatedwith lowering the basestation module from the tower top.

In a further embodiment the tower mounted equipment 10 of FIGS. 1-2 mayuse a waveguide rather than the communication cable 32.

Referring to FIG. 4, there is illustrated a plurality of basestationradio modules to be raised or lowered. Basestation radio modules 70 ₁-70_(N) (N: integer) are mounted on basestation module platforms 72 ₁-72_(N), respectively. Each of the basestation radio modules 70 ₁-70 _(N)may be same or similar to the basestation radio module 12 of FIGS. 1-2or the basestation radio module 12A of FIG. 3. Each of the basestationmodule platforms 72 ₁-72 _(N) may be same or similar to the basestationmodule platform 14 of FIGS. 1-2. Connection modules 74 ₁-74 _(N) areprovided to the basestation radio modules 70 ₁-70 _(N), respectively.Each of the connection modules 74 ₁-74 _(N) may be same or similar tothe connection plate 16 of FIGS. 1-2 or the connection plate 16A of FIG.3. The connection modules 74 ₁-74 _(N) may be formed in any electronicmodules (e.g., antenna system or any intermediate electronic systems) orform part of the tower. One or more than one communication cable (e.g.,32 of FIGS. 1-3) may be located at each connection module.

Each of the translating systems 76₁-76 _(N) may include the cabling and pulley system and the winch system44 of FIGS. 1-2 or any suitable alternative mechanism for raising orlowering the basestation radio module. The translating systems 76 ₁-76_(N) raise or lower the basestation module platforms 72 ₁-72 _(N),respectively. The translating systems 76 ₁-76 _(N) may directly raise orlower the basestation radio modules 70 ₁-70 _(N), respectively, withoutusing the basestation module platforms 72 ₁-72 _(N).

The connection modules 74 ₁-74 _(N) are detachably connected to thebasestation radio module 70 ₁-70 _(N), respectively and enable them tooperate, respectively. The connection modules 74 ₁-74 _(N) may belocated at different positions of the tower, and thus the basestationradio modules 70 ₁-70 _(N) may be enabled at different positions of thetower. The basestation radio modules 70 ₁-70 _(N) may be lowered formaintenance at different positions of the tower for maintenance. Alocation guide (e.g., 20 of FIGS. 1-2, 60 and 62 of FIG. 2) may beprovided for each basestation radio module 70 ₁-70 _(N) for properalignment.

In FIG. 4, “N” is an integer greater than one. However, “N” may be one.In FIG. 4, a plurality of translating systems 76 ₁-76 _(N) are shownseparately. However, the plurality of translating systems 76 ₁-76 _(N)may share some elements, such as power source.

There are number of technical advantages to placing RF electronics of abasestation at the tower top. One reason is that a single cable run(e.g., 32 of FIGS. 1-3) from the base of the tower to the top can beused to convey both power and data. Additionally, such electronics canbe used to minimize the number of cables required for MIMOfunctionality, for example. This eliminates the up front cost andmaintenance of multiple high quality RF cable runs normally required. Inaddition when receiver equipment is located at the tower base, cableloss directly impacts the receiver noise figure. RF power is alsodissipated in the cable runs making the power amplifiers less efficientthan those placed at the tower top.

One issue with tower mounted equipment in conventional systems is thecost to maintain the equipment, as specialized cranes and techniciansare typically required to access and service the equipment.Additionally, to avoid such maintenance costs, tower mount electronicscomponent costs are typically increased to realize a higher mean time tobreakdown failure rate than ground based equipment. Furthermore, circuitcomplexity is often increased to provision for redundant circuitrycapable of making the tower mounted equipment resilient to circuitcomponent failures.

By contrast, according to the embodiments of the present invention, ondetection of a fault in the tower mounted equipment a single operator(e.g., person or a control signal to the winch system 44) may lower thebasestation module from the tower top using the translating mechanism.Once lowered the defective component may be replaced or, alternatively,the entire module may be returned to the vendor for repair. The modulemay be returned to a factory for testing. New or repaired module thenwill be raised by the single operator to the tower top for service.

The maintenance arrangement/scheme of the embodiments of the presentinvention removes the requirement for a crane or specialized servicepersonnel to service tower mounted equipment. The arrangement of theembodiments of the present invention removes the insurance costsassociated with sending service personnel up the tower. The arrangementof the embodiments of the present invention reduces costs associatedwith over-provisioning masthead electronics. For example, Mean TimeBetween Failure (MTBF) of a ground based equipment may be used for themaintenance of the tower mounted equipment because of low cost servicemechanism hence reducing initial design costs and specifications.

The maintenance arrangement/scheme of the embodiments of the presentinvention removes the performance degradation in the receiversensitivity and PA efficiency associated with the cable runs requiredfor ground based radio transceiver modules.

The maintenance arrangement/scheme of the embodiments of the presentinvention enables high capacity data services based on, for example,MIMO OFDM, leading to lower cost per bit for the service.

The single communication cable arrangement (e.g., 32 of FIGS. 1-3) isapplicable to cable intensive basestation architecture, such as MIMOthat normally requires up to 18 cables, and thus increases the viabilityof the MIMO technology and the design flexibility of radio modules.
